A digital dual-clutch gearbox (DCT) dubbed ‘N e-shift’ is among the many most attention-grabbing of a collection of applied sciences being developed for Hyundai’s first high-performance electrical automobile (EV), the Ioniq 5 N.
In improvement onboard the N model’s ‘rolling lab’ idea known as the RN22ementioned N e-shift characteristic seeks to match the general really feel of a paddle-shift motion of the DCT in a petrol-fuelled N model.
There’s additionally meant to be an accompanying sound that mirrors the engine revs proper as much as the bap, bap, bap of the rev limiter, by way of audio system. A minimum of, that is the half the engineers are engaged on now in readiness for sign-off in round April or Might 2023.

“The thought is to come back fairly near the texture and sound of the DCT within the i30 N hatch,” mentioned Hyundai Government Technical Advisor and all-round N model guru Albert Biermann.
“That is what we need to ship, full with the identical jolt and downshift vibrations you expertise in our ICE N automobiles.
“Sound-wise, although, it is very difficult, particularly these pops and crackles you get within the i30 N, however we’re nonetheless engaged on this expertise to convey the DCT in-car expertise of a combustion engine automotive to comparable emotional ranges in our Ioniq 5 N EV.
“That is the goal.
“After we began constructing an Ioniq EV idea, 4 or 5 years in the past at our Namyang R&D middle, we have been simply utilizing inside audio system and so they weren’t sufficient, simply okay, so we added exterior audio system after which began simulating shift vibrations and forces you’ll affiliate with the DCT in an i30 N.
“However now, within the Ioniq 5 N, this improvement is on the stage of fine-tuning, however we’re actually not completed but, we’re nonetheless including issues just like the rev limiter and the assorted sound characters you may select between.
“I am calling it ‘VGS’ mode (Digital Grin Shift) and to activate it you hit a button on the steering wheel after which pull each paddles on the identical time to interact the digital shift mode.
“Clearly in visitors, you will not need to use paddle-shifters within the Ioniq 5 N, so that you simply flip it off by pulling each paddles directly, at the very least, that is how we’ve got it on the RN22e Prototype.
You may additionally be capable of alter regen ranges with the shifting, however we’re nonetheless engaged on that, as we’re with the character sounds.
“We name it N Sound Plus, and by the point we launch Ioniq 5 N, drivers will be capable of select from a number of totally different character sounds and even create and title your individual sounds.
“I anticipate you may additionally be capable of obtain new sounds over the air, which we create, however stuff like it will contain on-going improvement.”
Ioniq 5 N is anticipated to launch regionally on the finish of 2023 or in early 2024.
